DynastyMattress Cool Breeze 12-inch HD gel memory foam mattress is the most popular mattress by DynastyMattress for a good reason — it’s affordable, it’s very comfortable, and it works well for all sleeping positions. This is a medium-firm mattress so it has a lot of support (although it’s not the softest mattress in the world, of course). It’s made by a reputable company (founded in 2007), it comes with a 30-year warranty, and it’s 100% worth the money.

Best for:

  • Stomach and back sleepers — this mattress doesn’t sink and it’s both firm and supportive which is perfect for those who prefer these sleeping positions
  • Side sleepers — Dynastymattress Cool Breeze mattress provides enough softness to be comfortable for those who sleep on their sides
  • Those who don’t want to spend more than $300-$400 on a mattress — it’s one of the best mattresses in this price range

Not the best for:

  • Hot sleepers (those who often wake up at night sweating). The cooling gel makes this mattress cool to touch, but it will not keep a sleeper cool for all the night
  • Those who prefer sinkable mattresses — this one is closer to the firm end of the spectrum and most users don’t describe it as soft/sinkable

DynastyMattress Cool Breeze 12 inch gel memory foam mattress is one of the best options for the price (only the mattresses that are bigger than Dynasty King mattress are more expensive than $500).

Comfort features and specialties of DynastyMattress Cool Breeze 12-inch gel memory foam mattress

Material

DynastyMattress Cool Breeze 12-inch gel memory foam mattress consists of 4 layers and a fire barrier. According to the statistics, there are more than 300 mattress fire deaths every year in the United States, so it’s very logical that DynastyMattress put this barrier on their mattress.

According to the manufacturer, this barrier helps to slow the spread of fire — there is no information on the type of material this barrier is made from, but we can assume it’s made without using PBDEs (harmful and toxic chemicals). The thing is, this Cool Breeze mattress is CertiPUR-US certified, so it contains no ozone depleters, PBDEs, formaldehyde, heavy metals, etc.

As for the layers, it’s simple. Under the fire barrier, there is a 3-inch memory foam layer infused with the cooling gel. This layer does two things at once — it provides that cooling effect every hot sleeper needs and it contours the body.

Then, there are two 2-inch layers of air-flow comfort memory foam. The design of this material helps air flow in and out, so this layer makes the mattress fresh and keeps the sleeper cool by providing great air ventilation.

The bottom layer of this Dynasty memory foam mattress is 5-inch thick. It’s made of high-density foam and it makes New Cool Breeze what it is — a firm and supportive mattress.

Firmness and thickness

Dynasty Mattress CoolBreeze 12-Inch Gel Memory Foam 2

DynastyMattress New Cool Breeze 12-inch mattress is a medium-firm mattress. In short, it means that it’s a 5-6 on the firmness scale — it responds to pressure quickly and it’s not sinkable, but it’s also quite soft to the touch.

The good news is that this mattress is firm but it also has a good comfort layer and not hard as a rock — this means it provides a lot of support but it doesn’t create pressure points. However, when it comes to firmness, there is no such thing as one size fits all — so of course, some people are not happy with this mattress.

Thus, some users say that it’s too hard and that it’s even like “laying on a cement floor”, but such reviews are quite rare. What we can say here that this mattress is definitely closer to “firm” than to “soft”, so if you prefer plush mattresses, that’s not the right choice for you. Well, even if this DynastyMattress New Cool Breeze 12 inch gel memory foam mattress feels a bit firmer than expected, don’t worry — first of all, it will soften with time, and secondly, you can buy a soft topper to make this mattress more comfortable (it’ll cost you $40-$100).

As for the thickness, this Dynasty Cool Breeze mattress is 12 inches thick. Such mattresses can support your back and they really don’t sink – it’s a perfect thickness for back sleepers and those who suffer from back pain (but don’t take it as medical advice). However, 12-inch thick mattresses are typically not too comfortable, and Dynasty Mattress Cool Breeze is not an exception. Because of its thickness, this mattress will probably not work great for some plus-size side sleepers (not enough cushioning for hips and shoulders).

Edge support

Edge support is important — the mattresses with good edge support don’t sag on the edges, they increase sleeping surface, and they are more comfortable to sit on.

The DynastyMattress Cool Breeze 12 inch mattress provides great edge support. There is no built-in edge support here (e.g there are no steel rods in this mattress), but the high-density memory foam works even better than rods and heavy gauge coils. The memory foam mattresses are as sturdy and supportive on the edges as in the center, so you can sleep and sit close to the edge without any sagging on this DynastyMattress Cool Breeze 12-inch mattress.

Motion isolation

This mattress provides good motion isolation — memory foam is the best material for minimizing motion transfer because it localizes the movements of sleepers. In short, if your partner moves too much at night, you won’t feel it on this mattress. However, the level of motion isolation is not perfect — according to the reviews, some very light sleepers still have problems with it. If you are a very light sleeper, too, you should try a Twin XL DynastyMattress New Cool Breeze 12-inch gel memory foam mattress — two Twin XL mattresses isolate motion transfer much better than one King mattress.

Heat regulation

As we’ve said earlier in this DynastyMattress New Cool Breeze review, this mattress contains cooling gel. But does it make it a perfect choice for hot sleepers?

In short, it doesn’t. All Cool Breeze Dynasty mattresses are quite cool to touch and help to regulate the temperature with cooling gel, but if you are really a hot sleeper who wakes up in the middle of the night all sweaty, it won’t work well for you. Unfortunately, that’s the common problem of all memory foam mattresses — they are just not good enough when it comes to heat regulation, even if they contain gel-infused foam and air-flow memory foam.

Pressure relief

Dynasty Mattress CoolBreeze 12-Inch Gel Memory Foam 3

DynastyMattress New Cool Breeze 12-inch gel memory foam mattress is one of the best affordable mattresses (under $500) in terms of pressure relief. According to the reviews, this mattress is firm enough and offers a lot of support which means it just doesn’t create any pressure points. However, you should be careful with this mattress if you’re a plus-sized side sleeper — in this case, your hip might sink more than knees which may lead to poor alignment. The latter, in turn, can lead to pain, muscle strain, and discomfort.

Ease of movement

You can move on this mattress, roll over it, sit on it, and get out of it without any problems. The surface of the mattress doesn’t create any inconveniences so it’s also a good option for couples.

Compatibility with mattress bases

  • Slatted bed base is ok — the slats must be smooth and the space between the slats mustn’t be more than 4 inches.
  • Box spring is ok, too. If you want to make the bed higher, a box spring is what you need.
  • Platform base is fine, too.
  • Adjustable base. In most cases, this mattress works fine with adjustable bed frames. However, you should be careful with Twin XL mattresses if you have an adjustable Split King bed because according to some reviews, there can be center gap issues.
  • Floor — not the best option, but still ok. Just don’t forget to air your mattress frequently, clean the floor underneath it, and invest in a bed-bug-proof mattress encasement.

To sum up

This mattress is supportive — high-density memory foam provides both comfort, contouring, and support. It’s cool — not as cool as innerspring and hybrid mattresses, of course, but still quite cool. It’s affordable — the DynastyMattress Cool Breeze 12-inch gel memory foam mattress, Queen costs only $450. It works for almost all sleeping positions and for light sleepers because it has good motion isolation. Does it mean that you should buy it? Well, it’s up to you to choose. But if you are not a very hot sleeper or a plus-sized side sleeper, we can safely recommend this DynastyMattress product to you.

FAQ

Is this mattress a good choice for side sleepers and for back sleepers?

Yes. According to the reviews, only a few side sleepers had problems with this mattress (most often, it’s heavy people who didn’t feel enough cushioning). As for back sleepers, everything is great — this mattress provides a lot of support so if you sleep on your back, you’ll most likely love it.

How long does it take to air out this mattress?

Like all the other memory foam mattresses, this one has that slight chemical odor when new (some users claim that they had headaches because of the chemical smell). Let it air for 12-24 hours (48 in some cases) and the odor will go away.

Is this mattress firm?

Yes. It’s like 5-6 on a firmness scale, so if you want to sleep on a plush mattress, you should buy something else. This level of firmness is perfect for almost all sleeping positions because it offers a combination of comfort and proper support.
